WebClick here👆to get an answer to your question ️ A muon of charge - e and mass m = 207me (where me is the mass of an electron) orbits the nucleus of a singly ionized heliumatom (He^ + ). Assuming that the Bohr model of the hydrogen atomcan be applied to this muon - helium system, verify that the energylevels of the system are given by E = - 11.3 KeVn^2 Web19 Jan 2024 · a) Postulate of Bohr’s model of the H – atom 1) An atom consists of a small heavy positively changed nucleus at the centre and the electrons revolve around the nucleus in certain fixed circular paths called orbit. 2) As long as the electron remains in an orbit it does not lose or gain energy.
Web16 Dec 2024 · The Bohr Model of the Hydrogen Atom proposed the planetary model first, but an assumption about electrons was later made. The assumption was that the structure of atoms could be quantized. Bohr proposed that electrons orbited the nucleus in fixed-radius orbits or shells. WebThe Bohr radius is a physical constant representing the most probable distance between the electron and nucleus of a hydrogen atom at its ground state. In addition, the constant can be converted from meters to centimeters (5.29177 x 10 -9 cm), to nanometers (0.0529177 nm) or to angstroms (0.529 Å).

WebBohr Model of the Atom Fundamental postulates: The Danish physicist Niels Bohr, who first presented this model of the atom, based it on 3 fundamental postulates. (1) Electrons move around the nucleus in circular non-radiating orbits - called “stationary states”. However, they are not at rest! (2) An atom only emits or absorbs ...

WebBohr postulated that electrons orbit the nucleus in discrete energy levels, and electrons can gain and lose energy by jumping between energy levels, giving off radiation of frequency ν according to the formula Δ E = E 2 − E 1 = h ν where ν = 1 T, where T is the period of orbit, as in classical mechanics. irina mourach instagramWeb• Which of the following postulates of the Bohr model led to the quantization of energy of the hydrogen atom? A- The electron goes around the nucleus in circular orbits. B- The angular momentum of the electron can only be an integral multiple of h/2a. C- The magnitude of the linear momentum of the electron is quantized. irina meachemWebThe Bohr Model can be used for any atom, but the most common example you'll see is the Bohr Model for hydrogen. Remember that tough the Bohr model can be useful, it also is not completely accurate in the way it represents electrons around the nucleus.
